I keep the mindset of "I can't see why anybody would ever like me" and assume they're just being kind. Being lonely is better than being put in an embarrassing or disappointing situation from the misunderstanding.

I've never had that problem, i'm considered "nice" like when you first meet me *shy...* but then they realize i have a personality disorder and that every action i take, is just a copy of someone else's *disorder acting up there :l* - plus i'm pretty blunt sooooo if i'm flirting with you, i'll tell you, Like *cute guy* i'll say Wow, your face is hot, you wanna eat lunch? idk if thats good or bad but yea lol

Well i don't think that kindness has the same message for men and woman. When a woman is nice to a guy then the guy think's that maybe she is interested of course this is not the same with guys. When a guy is nice to a girl it can mean two things that he is interested or that maybe he just a nice guy. Then again there are many other thing that can go into this topic but i feel too lazy to type that all down but these are my two cent's on the matter PS Watch snafu(it's a anime) if you would like to go a bit deeper on the topic, show's you the world from a loner such as myself and how he perceives kindness.

I don't look like a nice guy..don't judge outer appearance. I'm tall, serious looking, whatever. But I have always been nice and courteous. But I have cut it down a lot because of people's attitudes. I used to open the door for people just out of courtesy, but time after time I get the ugly faces so I've stopped that. Being nice people think that your weak or they try to take advantage of you. It's sad. When I'm nice to a female I get the impression that they think I'm coming on to them. I guess girls get hit on a lot, so they automatically think you are flirting with them. I'm still nice sometimes, but I pick and choose now. But If I really see someone in need I'll be there to help.

Wow this is exactly my problem. When I'm nice to women or even smile at them they react as if I'm trying to hit on them...
And I get either get the turned down look or a look of approval from them(when im not trying to hit on them in the first place).
I would rather have them turn me down in that situation-because they simply leave after our interaction, but when they approve
They'll do their best to start flirting and the nicest thing that I could think to do in this situation is pretent that I don't know she's
flirting with me(smile and leave smile and leave slowly), but some catch on and know I'm turning them down

This has happened soo many times I now understand that either a lot of women are use to guys being nice with out an ulterior motive,
they simply accepted this stereotype: man + showing woman any attention = he wants me , or maybe I give off some vibe that I have
been cursed with to make my life just a little more awkward every day ( sigh* good times).

I have it happen to me all the time. I'll talk with a girl and since it's in my nature to be sweet it often gets taken as flirting. People always tell me I was flirting with someone and I have to explain that I wasn't and then they are always like, "SUUUURRREEE". Very frustrating.
